OP, damp brush when bowl lathering or face lathering, just give your brush a lazy shake or two. The bowl you choose matters (as does your soap/cream, brush and everything else, but really with any reputable soap or cream you'll be fine) some texture or ridges will make building a lather faster and easier. When bowl lathering I use a hammered copper bowl or my Timeless shaving bowl (find one on their website in the "Scratch & Dent" and thank me later). You can either load your brush directly from your soap puck or scoop a bit into your bowl. Golden rule of cooking applies... YOU CAN ALWAYS ADD MORE H2O but ya' can't really take it out. Your preferences on lather likely differ from mine and everyone else's on the forums and that's OK. Play around with it, you'll get there.
Please post a pic of that slow feeder bowl. I am genuinely intrigued. 2nd pic with lather earns bonus points...
Unfortunately I don't have a picture of lather in my bowl on hand, but there are YouTube videos on it. Stirling Collapsible Lather Bowl is the same thing I have.
If you skip to the 1:50 mark in THIS VIDEO you can see what I'm talking about. If you skip to the 4 minute mark you can see it in action. It really builds a lather fast.
